You find work function by extending the line on that stopping potential vs frequency graph until it hits the frequency axis, macha. That intercept's frequency is the threshold, and work function is just planck's constant multiplied by that. But I'll be honest, the last time I plotted a straight line correctly was to map the quickest route from my hostel to the mess, and even that was a optimistic projection.
